Hi Bernie
Adjust the microphone volume on the back knob, on the "out" output of the microphone settings and on the microphone's Mixer/EQ.
How do I use mine?
* Back button volume: 3pm
* Volume OUT of Mic settings: 100
* Mixer/EQ volume: 64
The settings will change a little more or less depending on the microphone.
I like to use one of the Knobs, which are close to the Joystick (Pitch bend), as microphone volume. Every time I turn on the keyboard I fiddle with them a bit and leave it at 12pm to reset the Mixer/EQ volume to 64. If I need to turn the volume up or down a bit, I use the Knob to do that. I use all my VH settings with the mixer volume at 64. As for the back button volumes and the "OUT" volume of the general Mic settings, there's no need to keep changing them.
I've been using the mic directly on the keyboard for a few years without any quality issues. By the way, I use a "Y" cable, to have two microphones connected.
